TYPEWRITING MACHINE Filed May 25, 1929 Patented Jan. 2, 1934 UNITED STATES TYPEWRITIVNG MACHINE Jesse A. B. Smith, Stamford, Conn., assignor to Underwood Elliott Fisher Company, New York, N. Y., a corporation of Delaware Application May 25, 1929. Serial No. 365,849

10 Claims.

This invention relates to typewriting machines and the like, and it has particular reference to embossing a work-sheet, such as a check, for example, to prevent its alteration.

In making out checks on a typewriter, according to this invention, the type may emboss the checks, by indenting or upsetting them, to render the check proof against alteration. This may be accomplished by the use of either ordinary type, or the usual check-perforating or fracturing type. Checks or other sheets may be embossed by feeding them in front of the mentioned soft rubber strip, and this strip becomes an embossing element, and converts a hard typewriter platen, at will, into an embossing platen.

Other features and advantages will herein after appear.

In the accompanying diagram,

Figure 1 is a perspective view of a platen and devices associated therewith for ink-copy manifolding and the embossing of checks or other paper.

Figure 2 is a partial sectional view of certain parts of Figure 1.

Figure 3 is a side sectional view of parts of Figure 1, showing in dotted lines parts in upraised position. I

Figure 4 is a cross-sectional view of related elements for record manifolding and for embossing the work-sheet.

Referring first to Figures 1, 2 and 3-of the drawing, the numeral 10 designates a frame including side plates 11 carrying a rotatable platen 12. An auxiliary ink ribbon 15 preferably used in manifolding a copy of the check, is disposed in front of the platen'at the printing zone and winds and .unwinds on a pair of spools 16 mounted on side plates 17 which are pivoted on the end portions of a rod 18, the rod being'supported by the side plates 11 of the platen-frame. Pins 11 and 11 project inwardly from the side plates 11, the former to limit the downward movement and the latter to limit the lifting movement of the plates 17 and the parts carried thereby. The plates 17 being pivotally mounted, it will be seen that the auxiliary ribbon is movable out of the printing zone, as shown in dotted lines in Figure 3. The mechanism for operating the auxiliary ribbon may be the usual mechanism or may be that shown and described in my ap-' plication filed March 24, 1927, and having the Serial .No. 177,884 (now Patent No. 1,764,900, dated June. 17, 1930).

The front end portions of the side plates 1'? form auxiliary ribbon-guiding. brackets and also hold vertically-disposed cylindrical pins 19, the free end parts of the brackets being arcuate clips 20 into which the pins may be removably sprung. A rubber strip 21 lying in front of, and in contact with, the auxiliary ribbon 15, has its ends secured to the pins 19 and is thus movable into and out of the printing zone with the auxiliary ribbon, although it may be supported independently of the plates 1'7 if desired, so that it may remain in the printing zone when the auxiliary ribbon is raised from said zone.

A record-sheet 25, on which an inked copy is to be manifolded, is shown in contact with the platen, being held in position by one of the auxiliary rolls 26, a feed-r0112? and a guide-finger 28. The auxiliary ribbon 15 is in front of, and in contact with, the record-sheet 25, and a work-sheet 30, which may be a check, for example, is disposed in front of, and in contact with, the band 21, which thus forms an embossing web for the check. A primary ink ribbon 32 passes through a guide 33, and a type-bar 35 is shown in front of the guide.

The embossing-web 21 is preferably a thin strip of soft rubber and is under tension when stretched between the two pins 19. -The embossing is accomplished on the check 30 by the types on the bar 35. rubber 21 allows the type to strike through to the record-sheet, the latter being inked by the auxiliary ribbon.

In typing checks, it is usual to type the name of the payee, and, in numerals, the amount to be paid, on one line, and on the line below theamount to be paid is typed in letters. For example, John Doe-$60.00 is typed on the first line and Sixty Dollars on the second line. For record purposes, only the first line may be printed on the record-sheet, and if no record is to be made when typing the second lineon the check, the auxiliary ribbon may be temporarily raised from the printing zone, so that no impression will be made on the record-sheet.

If it is desired to emboss the amount line of the check, without manifolding, then the ribbon may be moved from the printing zone, in any wellknown manner, leaving the rubber embossing strip 21 in the printing zone.

It may at times be desirable to emboss a sheet to protect against alteration everything typed on it; in this case the auxiliaryribbon may be removed and the embossing web will remain in the printing zone. It may be desired to make a record copy of both first and second lines on the check, and in this case the auxiliary ribbon 15 will remain in working position.

Referring to Figure 4, the same relation of parts obtains as in Figure 2, except that a carbon-- sheet 15 is substituted for the auxfliary ribbon 15, which is done when a carbon-copy instead of a ribbon-copy is to be made.

It will be noted that the auxiliary ribbon 15 may be removed temporarily from the printing zone,

and successive lines maybe embossed on a work sheet without manifolding; that with the ribbon Thus, for manifolding, the tensioned name, and numeral-amount on the check, and then restore the web 21 to its embossing-line position, to emboss the printed word-amount upon the amount-line of the check; and that the shifting of the frame 1'7 up or down immediately changes a standard platen and, standard printing types into co-operating embossing elements, so that printing and embossing may be alternated at will.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:

1. In a typewriting machine, the combination with a primary printing ribbon and an auxiliary printing ribbon, of a protecting rubber blind between said ribbons, said blind being sufficiently yieldable to allow the type to emboss a work-sheet.

2. In a typewriting machine, the combination with types and a hard cylindrical platen, of a tensioned soft rubber stationary strip covering the printing zone of the platen, said strip being yieldable to each impact of the types sufllciently to emboss a check-sheet, said platen being rotatable independently of the elastic strip, and means to co-operate with the platen to feed the cheeksheet, means being fed between the elastic strip and the cylindrical platen, effective to preserve a manifold record of the characters embossed on the check-sheet.

3. In a typewriting machine, the combination with types, a hard rotatable platen and a platenframe of a tensioned soft rubber strip mounted by means of a movable carrier upon the platenframe, to be interposable at will between the platen and a check, to yield to the type-blows and produce embossed characters on the check, and means co-operating with the platen to feed the check past the embossing strip, and also operative to feed worksheets when the embossing strip is withdrawn from working position.

4. In a typewriting machine, the combination with a hard rotatable platen and striking types, of means for converting the machine into a check-embossing machine, including a soft rubber strip and a movable carrier upon which it is mounted for interposition at will between the platen and a check, and effective to emboss the check.
